IMPROVEMENT IN APPARATUS Pen REFRIGBRATING AND MAKING- ICE.

The Schedulefefermd toxin these Letters Patent and makingfpart of the same.

Be it known that I, HOMER Y'ArttZ-Am'of Nashrille, in the State'of Tennessee, have invented an I'm- -provementin Apparatus for Refrigerating Fluids and Making Ice; and the following is declared to be acor- -This invention relates'to an apparatus :iinwhioh ether or other liquid isevaporated 'i'n-wmmmflhr ma-l:- ing'ice or cooling. fluids or liquids. xln' my apparatus a large surface'forevaporationis obtained, and only a small quantity of the yolatile fluid is required. Two different fluids or liqni'dsjoanbe simultaneously refrigerated. I y The apparatus is. very simple. in construction, and f contains a large extent of cooli|1gsurfi ce in a small space.

In, the drawing- Figure lis a sectional plan of the. apparatus, and" Figure 2is a section jtransyersely the evaporat= ihe tubes a a 'areiconnected at their ends, to forn z't-hori'zontal coil,- and around each tube dis a second tube, 1), forming a jacket, and these are oonnected to each other, as at c, tofomn-"a second worm.-

. The tubes orarewit-hin the tubes 7), and rest upon them at the bottom, and, theethr ou other volatile liquid is introduced in the pipes b, so"'that they are abouthalffull. I p

This constructionfurnishes a large surface for the evaporation of the ether, and ample space for the va-' pors to pass away to the air-pump,through the tubes These tubes d tandem-e arranged as'shown in fig 1, to equalize-the vacuum-action 'tlu'oi'ighout' the" apparatus;

The aforesaid pipes are introduced in a shallow vessel, f, with a cover that. may be;mov-able, if desired,-

and within this vessel) are the screens 9 g, and pipes hit are. provided at the respective ends.

It will now be understood that this apparatus can be employed in cooling or refrigerating two liquids or fluids at one and the same-time. Forinst-ance:

a later 01-0'Elli' liquids can be circulated through the tubes to a,and only cooled to the proper temperature for may be cooled by being passed througl'i theyessel f, and usedfoucooling roorns,dwellings, hospitals, 8w,

This arrangement of cooling both air and water at thesam'e time beingof great importance to brewers, whereby the beer is cooledby acirculat-ion of cold water, while the rooin'is kept atthe proper temperatut-e farm-able to, fermentation, and, ventilateilof its noxious vapors as well.

The horizontal tubes it within the tubes 1), park with the vesself, inelosing such tubes, so as to refrigerate simultaneously two fluids or liquids, substans tially-as set forth. j p
